Yarn Count Explained: A Practical Buyer's Guide (Nm, Ne, Tex)

If you have ever received a yarn quote and wondered what "30Nm" or "20s Ne" actually means for your fabric, you are not alone. Yarn count is the single most misunderstood spec in textile sourcing, yet it decides how your finished product feels, drapes and costs. This guide breaks it down.

What yarn count measures

Yarn count expresses the relationship between a yarn's length and its weight. A higher count = finer yarn; a lower count = thicker, heavier yarn. The confusion comes from the fact that different systems flip the ratio, so the same number can mean opposite things depending on the standard.

The three systems buyers meet most

• Nm (Metric count) – most common for worsted, wool and blended yarns in Europe and Asia. Nm 30 means 30 kilometres of yarn weigh 1 kg. Higher Nm = finer.
• Ne (English cotton count) – standard for cotton and cotton-rich yarns. 20s Ne is a medium yarn; 30s/40s Ne are finer. Also inverse: higher Ne = finer.
• Tex / Dtex – weight-based, used for filament and technical yarns. Here a higher number means a heavier yarn (grams per 1000 m for Tex).

Which count should you specify?

• Knitwear & sweaters: Nm 28–60 (or 20s–40s Ne) covers most lightweight to mid-gauge work.
• Socks & hosiery: Nm 24–34 with nylon plating for durability.
• Weaving / upholstery: Nm 10–24 for heavier, stable fabrics.

A note on consistency

Count is only useful if the mill holds it tightly. At TIANSHENG we hold count tolerance within ±2% batch to batch so your production stays repeatable. If you are matching an existing sample, send us the yarn and we will reverse-engineer the count and composition for you.
